I'm trying to install Atv-win--3.0 on an 1st gen. I've made the USB drive, everything installs, so it seems, no errors. I take the USB drive out of the ATV unplug, plug in, it's starts up but nothing is installed. What am I missing. I'm using a PC. The firmware is 3.0.2. Thanks for the help. I'm a newb at this.
